2.3 Restart Test
When the PBX starts up, it will automatically carry out a self-test complete with
RAM test if the HEX rotary switch on the mainboard is set on position 0 or 2.
The RAM can be tested in two ways:
• RAM quick-test (normally approx. 3 seconds):
HEX rotary switch in position 0.
• RAM thorough test (up to 1 minute, recommended with every new installa-
tion):
HEX rotary switch in position 2.
The system's self-test including the RAM test is signalled by vertical bars moving
up and down on the 7-segment display.
Once the startup process has been successfully completed, the decimal point on
the 7-segment display flashes regularly (see "Basic System Self-test", Page 7.62).
Any errors during the startup process are signalled on the 7-segment display (see
"Operating State and Error Displays", Page 7.58).
If a RAM error occurs, replace the mainboard (see "Replacing the 2025 / 2045 or
2065 Mainboard", Page 7.33).
Note:
Never remove any cards while the system is still connected to the power
supply.
Putting the PBX into Operation
1. Remove the PBX cover.
2. Set the HEX rotary switch on the mainboard to position 0 or 2.
3. Reconnect the PBX to the power supply.
The PBX starts up.
